Abstract

See full text

A device for use in pressure sensing such as hydrocephalus shunts, having a housing enclosing a chamber with at least one port communicating with the chamber. A wall of the chamber includes a flexible portion or thin diaphragm that deflects with transitions in pressure to contact an upstand structure of the housing. A pressure sensor is contained within an enclosure sealed from the chamber by a flexible membrane and which receives fluid pressure from the chamber. This arrangement allows for calibration of the device by identifying a knee feature in pressure data associated with the diaphragm making contact with the upstand.
